N2 - In the present work, we report the synthesis and characterization of two new heterometallic coordination polymers based on CeIII and containing CoII or CuII cations, assembled by the bifunctional ligand 1H-imidazole-4,5-dicarboxylic acid, [Ce(H2O)2(HIDC)Co(IDC)]·H2O CoCe and [Ce(H2O)2(H2IDC)Cu(H2O)(IDC)Cu0.2(H1.6IDC)] CuCe. Compound CoCe was obtained under one pot hydrothermal synthesis, while CuCe was synthetized by a step by step synthesis using the metalloligand [Cu(H2IDC)2(H2O)2] Cu1, as precursor. From a structural point of view CoCe presents an intrincated 3D covalent structure, in which alternating λ-Δ chiral CoII chains can be observed, which are assembled by discreet CeIII fragments, giving rise to the 3D structure. Meanwhile, CuCe presents a structure formed by [Cu2Ce2] heterometallic chains, partially assembled by CuII cations in a 2D covalent structure. Magnetic properties reveal that both CoCe and CuCe presents a global antiferromagnetic behavior, dominated by the interaction between CoII-CoII or CuII-CuII entities connected by μ2-κN,O-κO''',N' bridges, belonging to H3IDC anionic derivatives. Moreover, a weak ferromagnetism phenomenon was found in compound CoCe, corroborated by hysteresis loops and ac magnetization.
